DANGER

AVOID CREATING DUSTPOSSIBLE CANCER AND LUNG DISEASE HAZARD

While Bendix Spicer Foundation Brake LLC does not offer asbestos

brake linings, the long-term effects of some non-asbestos fibers

have not been determined. Current OSHA Regulations cover

exposure levels to some components of non-asbestos linings but not

all. The following precautions must be used when handling these

materials.

1. AVOID CREATING DUST. Compressed air or dry brushing must

never be used for cleaning brake assemblies or the work area.

2. BENDIX SPICER FOUNDATION BRAKE LLC RECOMMENDS THAT

WORKERS DOING BRAKE WORK MUST TAKE STEPS TO MINIMIZE

EXPOSURE TO AIRBORNE BRAKE LINING PARTICLES. Proper

procedures to reduce exposure include working in a well ventilated

area, segregation of areas where brake work is done, use of local

filtered ventilation systems or use of enclosed cells with filtered

vacuums. Respirators approved by the Mine Safety and Health

Administration (MSHA) or National Institute for Occupational

Safety and Health (NIOSH) should be worn at all times during

brake servicing.

3. Workers must wash before eating, drinking or smoking; shower

after working, and should not wear work clothes home. Work

clothes should be vacuumed and laundered separately without

shaking.

4. Material safety data sheets on this product, as required by

OSHA, are available from Bendix Spicer Foundation Brake LLC.

Model ES-165 and EB-165 Interchangeability

Brake parts for the Extended Service Brake (Model ES-165) are unique

and must not be intermixed with Standard Brake parts (Model EB-165)

unless otherwise instructed. These parts consist of the camshaft,

camshaft washer, return spring, cam roller and shoe/lining assembly.

Any attempt to operate the brake with other than its intended parts may

result in unsatisfactory performance.

“On-Road” Repair: If a vehicle should need “On-Road” repair and

ES™ Brake hardware is not available, it is possible to retrofit the brake

with Standard Brake parts in order to return the vehicle to service.

These parts consist of the Standard shoe/lining assembly, cam roller,

pin and return spring. The retaining springs and camshaft with cam

washer will work in this situation and do not need to be replaced.

EB™ Roller and ES™ Cam Interchangeability

The EB™ Roller and the ES™ Cam are compatible and can be used

together. Figure 5 illustrates the proper fit of an EB™ Roller to an

ES™ Cam. As shown, the contact pattern is at two points and the

two parts will function satisfactorily with this fit.

NOTE: The ES™ Roller and EB™ Cam are not compatible and should

not be used together.

Brake Adjustment - Manual Brake Adjuster

NOTE: An assistant is required to make a brake adjustment.

WARNING: Block all wheels before beginning this adjustment

procedure.

To determine whether Bendix Brakes require adjustment, applied

stroke is measured and compared to the maximum value for the air

chamber size in use on the vehicle.

1. Perform “Brake Maintenance Preliminary Steps” described earlier.

2. With air chamber pushrod fully retracted, measure distance from

face of air chamber to centerline of clevis pin hole. Refer to Figure 8.

If the measurement is not within ranges shown in Table 2, reposition

clevis. Remeasure the distance and repeat until within range. Record

exact measured distance as dimension “A”.

Due to the importance of a well-maintained brake system, the

inspections and maintenance listed below must be accomplished

by commercial vehicle operators at the intervals suggested.

Since driver technique and vehicle use affect the rate of brake

component wear, it may be appropriate to increase the frequency

of the following inspections to fit individual needs based upon past

experience.

Brake Maintenance Preliminary Steps

Prior to performing any maintenance requiring removal of the tire

and wheel, the following preliminary steps must be taken to ensure

your safety. Refer to Figure 7.

Figure 7. Vehicle Maintenance Support

1. Set parking brake and block wheels to prevent vehicle

movement.

2. Raise drive axle with a jack and support on suitable stands.

WARNING: Never work under a vehicle supported by a jack.

3. Cage spring-type brake chamber following vehicle

manufacturer’s instructions.

B

Measure ThisDistanceat 80 psi,Dimension “B”

3. Apply and hold an 80 psi brake application, and again measure

from face of air chamber to clevis pin centerline. Refer to Figure 9.

Record distance as dimension “B”.

5. Take “A” dimension exactly as before. Take “B” measurement

using a lever to move brake adjuster as shown until the shoes

contact drum. Refer to Figure 10. The result of “B” - “A” is brake

free stroke. Adjust free stroke to within range specified in Table 3.

6. To adjust free stroke, depress locking sleeve on brake adjuster

adjustment nut and turn in direction required. Recheck free stroke

to verify it is within range. Make sure sleeve is “locked” when

adjustment is completed.

7. Verify that brakes are not dragging by spinning wheels by hand

or tapping drum lightly with a hammer and listening for a sharp

ringing sound.

8. Perform Brake Operation Check, to verify proper operation of

brakes before releasing vehicle for service.

Brake Adjustment - Automatic SlackAdjuster

NOTE: A properly working Automatic Slack Adjuster does not require

manual adjustment while in service. The manual adjuster hex is

intended for use during adjuster installation and brake overhaul.

WARNING: Automatic slack adjusters must never be repeatedly

adjusted to correct excessive in service pushrod stroke, because this

condition indicates that a problem exists with the automatic adjuster,

with the installation of the adjuster or with related foundation brake

components which manual adjustment will not correct.

1. Brake adjustment for automatic slack adjusters is the same as for manual

brake adjusters.

2. Refer to the Automatic Slack Adjuster Manufacturer's Instructions for proper

installation.

NOTE: If adjustment is necessary, Bendix Brakes are adjusted to

achieve proper free stroke. The difference between free stroke and

applied stroke is merely the method used to move the brake adjuster

from rest. Applied stroke uses an 80 psi brake application; free

stroke is measured using a lever to move the brake adjuster until the

brake shoes contact the drum. If applied stroke exceeded the

maximum and adjustment is necessary, adjust the brakes as

described in steps 5 through 8 below.

4. Subtract dimension “A” from “B”. The difference is applied stroke.

Compare applied stroke to maximum value in Table 3. If applied

stroke equals or exceeds maximum applied stroke shown, adjust

brakes. If less than the maximum, no adjustment is required and you

may perform Brake Operation Check.

Brake Operation Check

NOTE: An assistant is required to make a thorough brake operation

check.

1. Apply brakes to 80 psi and hold. Check all air line fittings and air

chambers for leakage.

2. Apply and release brakes while observing operation of brake

adjusters on each axle. As brakes are applied and released, brake

adjusters should move in unison visually.

3. Investigate source and make corrections for any discrepancies

found in Steps 1 and 2.

!

4. Drive vehicle at low speeds in a safe area and make several brake

applications to verify safe operation and absence of pulling,

grabbing, or noise. If any of these are noted, investigate and repair

prior to releasing vehicle for service.

CAUTION: Never release a vehicle for service if any brake

discrepancy - no matter how minor - is evident.

Lubrication

When servicing brakes or replacing components, lubricate per guidelines listed in Lubrication Table below.

Lubricate the following components with grease specified in table:

• One-piece Roller —lubricate shoe roller recess.

• Two-piece Roller—lubricate shoe roller I.D.

• Roller and anchor pin recesses of each shoe on ES & ED 150-4L models

Do Not Lubricate The Following:

• Cam head surface or related parts that contact cam head surface. For efficient operation, the cam head surface must remain free of oil,

grease or other contaminants.

Note: When lubricating the camshaft bracket, lubricate until grease comes out at the brake adjuster end.

The seal is installed at this end with the air side in so that grease purges out.

CAUTION: Do not use moly-disulfide loaded grease or oil because this may shorten service life.

Important: In no case should the lubrication interval exceed the published intervals in table below.

Component Lubrication Interval Type of Lubricant

Standard Every 50,000 miles or every 3 months Standard Chassis Grease

LMS-Low Lube Every 250,000 miles or once a year* Mobilith SHC-460 Synthetic

LMS-Lube Free None* Mobilith SHC-PM Synthetic

Table 4. Lubrication Intervals

Note: The Bendix LMS-Low Lube brake uses a special “button head” grease fitting. This helps identify the system as an LMS BrakePackage and also indicates that system should be lubricated with a Bendix approved synthetic lubricant.

The Bendix LMS-Lube Free brake is lubricated at the factory with Mobilith SCH-PM synthetic grease and does not require lubrication atservice intervals. There is no grease fitting on the LMS lube free components.

Brake Adjuster Lubrication: Pressure Iubricate according to manufacturer’s instructions.

After removing the brake parts to be serviced, the following

cleaning procedures should be followed:

• Wire brush all parts exposed to mud, road dirt, and salt,

including spider, air chamber bracket, dustshields and exterior

of drum.

CAUTION: A layer of oxidation and dirt on the outside of a

brake drum acts as an insulator and may hinder normal

heat dissipation. Remove excessive deposits by wire

brushing.

• Use a vacuum cleaner to remove brake dust from drums. Wipe

interior of drums with a greaseless solvent to remove any

spilled oil.

WARNING: The long term effects of non-asbestos fibers,

have not been determined. Therefore, precautions should

be used when handling these materials. Do not use

compressed air to blow from interior of drums. Brake lining

dust, when inhaled, can be injurious to health.

Cleaning Brake Parts

31

Drum Inspection

Bendix does not recommend the turning or reboring ofbrake drums. The reduction of wall thickness reduces theamount of thermal energy that can be absorbed by thedrum during braking. Also, the decrease in wall thicknessincreases the amount of deflection for the same input load.Both of these are undesirable. If drums are refaced oroversized, the new diameter MUST NOT exceed themaximum diameter marked on the drum during its servicelife.

• Clean all remaining brake parts thoroughly with a suitable shop

solvent. Wipe dry with a clean, lint-free cloth.

NOTE: This information is general in nature. For specific brake

drum inspection guidelines, refer to the drum manufacturer’s

instructions.

1. Check for cracks, heat-checks, glazing, grooving, run-out and

out-of-round. Refer to Figure 34. Cracked drums must be

replaced. Drums which are glazed, grooved, out-of-round, etc.,

may be returned to service if they can be repaired without

exceeding manufacturer’s maximum diameter or run-out

specifications.

2. Check drum diameter. Replace drum if it exceeds maximum

diameter stamped in drum.

CAUTION: Under no circumstances should drum be used if

it exceeds manufacturer’s recommended maximum

diameter or run-out specification.

4. Check the linings and replace with Bendix OEM grade shoe and

lining assembly if contaminated, cracked, or worn to less than 1/4"

(6.4mm) thickness at any point (see instructions below) or 3/16"

(4.5mm) for EB/ES 150-4L brake.

NOTE: To eliminate premature Lining Replacement Bendix recom-

mends the use of the Bendix Brake Lining Wear Gauge to accurately

measure lining thickness. This tool is available through Bendix as

BW7261.

Important: For use with air actuated cam brakes where minimum

allowable lining

thickness is 1/4 in.

(Note: Do not use for

strip linings on 15 x 4

brakes or similar

brakes.)

1. With the brake not

applied, place the tip of

the gauge between the

two lining blocks,

between the top of the shoe table and drum. Use the gauge to scrape

away any mud, rust, or other contaminants that could interfere with

proper lining measurement.

2. Remove the gauge from the brake.

3. With the vehicle’s brakes applied, try to put the gauge between the

two lining blocks and the top of the shoe table. Note “hook” of gauge

allows insertion around worn drum lip. If the tip of the gauge will not

fit between the brake drum and the top of the shoe table, the lining is

worn below 5/16 inch

and will need to be

replaced.

4. If the tip of the gauge

fits between the brake

drum and the shoe

table, the lining is not

worn below 1/4 inch at

this time.

5. Because brake shoes can wear at different rates, check both shoes

on each brake and all brakes on the vehicle.

Shoe and Lining Inspection

1. Check shoes for bent or cracked webs, or table, broken welds,

loose rivets or elongated rivet holes. Refer to Figure 36. If any are

found, replace with Bendix OEM grade lining and shoe assemblies.

2. Check anchor pin and cam roller contact areas in shoe webs for

elongation or wear. Replace shoe if diameter exceeds the following

specifications.
